Sunan Ibn Majah 340
It was narrated that 'Abdullah bin Ja'far said:
"The thing that the Prophet most liked to conceal himself behind when relieving himself was a hillock or a stand of date-palm trees."
حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا مَهْدِيُّ بْنُ مَيْمُونٍ، حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي يَعْقُوبَ، عَنِ الْحَسَنِ بْنِ سَعْدٍ، عَنْ عَبْدِ اللَّهِ بْنِ جَعْفَرٍ، قَالَ كَانَ أَحَبَّ مَا اسْتَتَرَ بِهِ النَّبِيُّ ـ ﷺ ـ لِحَاجَتِهِ هَدَفٌ أَوْ حَائِشُ نَخْلٍ .
